Mass Concrete for Harbor Bridge in Corpus Christi, Texas

NITROcrete delivered project savings in the six-figure range by controlling temperature and eliminating the need for cooling tubes.


  • 70° F / 21° C
  • US 181 Harbor Bay cable-stayed suspension bridge in Corpus Christi, Texas
  • Two mass concrete bases
  • Tallest structure in South Texas with 500-foot-tall towers
  • Owner: Texas Department of Transportation


  • Mass concrete, high specification
  • High humidity and ambient temperatures near the Gulf of Mexico
  • Extreme temperature control required to avoid excess temperature differential in forms
  • Tallest structure in South Texas


By reducing temperature without the need for cooling tubes, contractor saw savings in the six-figure range. Cooling with liquid nitrogen reduced the temperature differential in the forms to prevent thermal cracking. The customer and project gained consistent cooling and thereby mitigated downtime with concrete cooling even as temperatures rose.

About NITROcrete™

NITROcrete is the world leader in concrete temperature control. In 2012, what started as a jobsite problem for a partner evolved into a solution that is revolutionizing the concrete industry. The team listened, tested, developed prototypes, and made adjustments. Then they listened more, tested more, and in 2017, after 5 years of R&D, they introduced NITROcrete, a comprehensive concrete solution born directly out of the concrete industry.

The largest concrete companies in the world now use NITROcrete to simplify their processes, streamline their operations, and grow their bottom lines. NITROcrete provides a comprehensive concrete solution–cooling, system management, and support–which gives its worldwide industry partners unmatched efficiency, control, and peace of mind.


  • Contractor savings in the six-figure range
  • Eliminated cooling tubes for cost and operational benefit
  • Reduced temperature differential in concrete forms to prevent thermal cracking

Six-Figure Savings by Eliminating Concrete Cooling Tubes on Harbor Bridge

Corpus Christi's iconic Harbor Bridge required mass concrete for 500-foot tall towers. High humidity and ambient temperature required extreme temperature control to avoid complications with the concrete in the forms. NITROcrete™ enabled the project to meet temperature specifications without concrete cooling tubes, saving time and expense.
